Speaker Dock compatible with iPhone 3GS

I'm looking to buy a speaker dock for my iPhone 3GS. Do you have any suggestions for a good buy? I'm not really an audiophile and don't want to spend more than about $200. Also, all I care about it doing is playing my iPhone's music - don't care about a clock or alarm or anything.

So far the best option I've found is the Logitech Pure-Fi Elite High-Performance Stereo System - $134 on Amazon. Anybody have any experience with this model? Any others worth checking out?

don't get the IH70 although it sounds great and says it's compatible with ipod touch. so everytime i plug it in it gives me a warning that there is a lot of interference and I get a lot of interference when playing music.

Basically make sure it says it's compatible with the iphone and not just the ipod touch.
